SC16C550B Overview
Description
The SC16C550B is a Universal Asynchronous Receiver and Transmitter (UART) used for serial data communications. Its principal function is to convert parallel data into serial data, and vice versa.
Key Features
- 5 V, 3.3 V and 2.5 V operation
- Industrial temperature range
- After reset, all registers are identical to the typical 16C450 register set
- Capable of running with all existing generic 16C450 software
- Up to 3 Mbit/s transmit/receive operation at 5 V, 2 Mbit/s at 3.3 V, and 1 Mbit/s at 2.5 V
- 5 V tolerant on input only pins1
- 16 byte transmit FIFO
- 16 byte receive FIFO with error flags
- Programmable auto-RTS and auto-CTS In auto-CTS mode, CTS controls transmitter In auto-RTS mode, RX FIFO contents and threshold control RTS
